To all abomttmay concern:

Be it known that I, CHARLES WILLIAM Zasrnow, a citizen of the UnitedStates, residing at Arundel Cove, in the count of Anne Ar'undel andState of Maryland, ave

- and combination ofinvented certain new and useful Improvemen-ts 'inEvaporating'Ap aratus', of which the following is a speci cation,reference being bad therein to the accompanying drawing. V I

This invention useful improvements in apparatus for evaip ora-ting ordistilling water or other liqui s, and has for its principal object toprovide an apparatus which. is particularly adapted to-heused at sea forevaporating salt water.

A further object of the invention is the provision of an a paratus whichwill be simple in constructron, and one which may be easily cleaned andreadily accessible in case'of repairs.

A still further object of the invention is the provision of an apparatuswhich will.

effectually prevent any traces of salt water being carried into theupper part of the eva crating still.

Vt ith' these and other objects in view, the invention consists of thenovel construction scribedand claimed.

In the drawings :Figure 1 is a vertical section through. an apparatusembodying my present invention, some of the steam coils being removed.Fig. 2 is a cross sectional view thereof taken on the'line 22 of Fig: 1,and 'Fig. 3] is a similar view taken on the line 3-3 of Fig. 1. I

. In carrying this invention into practice I preferably make use ofacasing or recepjtacle 1, which in the present instance isin the -formof a vertically arranged cylinder,

the same'being closed at its to and bottomor compartment. In thisconnection t is relates to" certain new and" parts hereinafter (le 'tobe noted that in devices of this character where the heating coils areimmersed, foammg 1s liable to occur in the evaporator, and

.i if such does occur, the baflie plates will break upethe globules ofsteam and water and the 11 rated steam may then pass to the steam spaceabove the plates and then to the condenser without carrying traces ofsalt water. The heating medium used in connection with this apparatus ispreferably steam, the

same" being fed through a pipe 7, passing through a suitable stufiingbox '8 centrally arranged u on the head 2 of the cylindrical casing. Tis pipe is arran ed longitudinally of the casing and is cei itrallylocated therein, the same extending through the perfor'ated bafii'eplates and into the water compartment, and being connected to an uppermanifold 9 by a pipe 10' which is arranged at a right angle to the inletpipe. A series of coils 11 connect' the upper manifold 9' with a lowermanifold '12, which manifold '12 is connected in any. suitable manner toan outlet pipe 13. The outlet pipe 13 is also arranged longitudinall ofthe cylindrical casing and centrally ocated with regard.

thereto, the same passing from the water compartment througha stuffingbox' 14 on the casing. In this manner live steam is "lied from asuitable generator to the steam heating coils 11, which coils serve tothoroughly heat the water within the compartment i and generate steam,whichsteam rises and passes through the perforations in the baffleplates and is collected within the compartment 5 from which itcscapesthrough the outlet pipe 15 and is led away to any suitable form ofcondenser in which it is condensed into purified water or other liquid,according to the class of work which is being performed.

A suitable gage 16 is provided for the purpose of determining at anytime the amount of water in the casing, and a steam gage 17 is shown indotted lines and serves to indicate the steam pressure occasioned by thesteam generated in the casing. ll also provide a suitable safety orblow-oif valve for'the steam compartment, the same being indicated at18in dotted lines, and a blowoff valve 18 arranged in the lower manifoldfor a urpose which will be obvious.

In t epractice of my invention the water or other liquid to be purifiedo1; evaporated is carried into the water compartment through'a pipe 19,and the same is converted .into 'steam. in the manner heretoforedescribed whereupon said steam is conveyed from the casing and condensedinto purified liquid. The heating apparatus used for gencrating thissteam, as will be noted, has an inlet pipe and an outlet pipe which arecen trally located within the casing, said piifipes passing through theupper and lower stu ng boxes as heretofore described and being adaptedto turn within the same, so that the heating apparatus as a whole may berevolved upon its vertical axis to facilitate the cleaning and scalingof the salt and other defects which have been deposited on the heatingsurface. A suitable door is indicated at 20 which closes the opening inthe side of the casing, and it will be readily understood that any oneof the heating coils 11 may be brought opposite the opening when it isdesired to clean the same, thus obviating the necessity of removing thecoils from the apparatus. It is also to be noted that any one of thecoils may be taken out through this opening and another set up in itsplace without the necessity of disturbing any other coil. Furthermore,suitable connections between all of the parts contained. within thecasing are provided, which will permit the entire apparatus being takenapart within the casing and removed therefrom through the opening in theside'of said casing. This will be perfectly obvious upon an examinationof the drawing, it only being necessary to state that a coupling 21 inthe inlet pipe is used so that the upper section of the inlet 'pipe maybe disconnected and withdrawn through the top of the casing; and acoupling 22 is used for the outlet pipe which al lows the ipper sectionthereof to be lifted within the casing and withdrawn through the openingin the casing.

It will therefore be understood that I ac complish the object of myinvention by means of an apparatus which is simple in construction andoperation and well adapted to accomplish the result for which it is.intended, and furthermore, the parts are so connected that they may beeasily disconnected and taken'from theapparatus when necessary, and mayalso be easily cleaned without taking them from the apparatus.

What I claim is 1. An evaporating apparatus, comprising a casing orreceptacle having liquid and steam spaces therein, an opening withinsaid casin asteam inlet pipe centrally located therein and journaledupon said casing, a steam outlet pipe also journaled upon the casing inline with the inlet pipe, stulfing Witnesses:

boxes for'hoth of said journals, and steam as heating coils connectingthe inlet with the outlet pipe, said coils adapted to be re-- volved asthe inlet and outlet pipes are rotated within their respective bearingswith out releasing any of the parts or connections 5 ofthe inlet andoutlet pipes.

' 2. An evaporating apparatus comprising a vertically arranged casinghaving liquid and steam spaces therein, an opening in said casing, asectional steam inlet pi entering the casing at the upper end t ereof,the same being journaled u on the casing, a detachablecoupling for t esections of said inletpipe located within the casing and adjacent theopening therein, a circular manifold connected to said inlet pi e, aplurality of steam heating coils depem ng from said circular manifoldand connecting the same with a similar manifold, and an outlet pipeconnected with said second mentioned maniso fold and journaled upon thecasing in line withtheinlet pipe, stufiing boxes for both of saidjournals, the entire steam apparatus adapted to be revolved withoutreleasing any of its parts or connections as the inlet 8d and outletpipes are rotated within, their respective bearings, substantially asand for the purpose specified. I

3. An evaporating apparatus, comprising a vertically arranged casinghaving liquid as and steam spaces therein, an opening in said casing, asectional steam inlet pipe entering the casing at the upper end thereof,the same being iournaled upon the casing, 21. detach able coupling forthe sections of said inlet .95 pipe located within the casing andadjacent the opening therein, a circular manifold connected to saidinlet pipe, a plurality of steam heatin coils. depending from saidcircular manifo d and connecting the same with a similar manifold, asectional outlet pipe connected with said second mentioned manifold andjourneled upon the casing in line with the inlet pipe, stufliug boxesfor both of said journals and a detachable coupling for 1 05 thesections of said outlet pipe located outside thecasinlg, the entiresteam apparatus adapted to be revolved without releasin any of its partsor connections as the inlet and outlet pipes are rotated within theirre- 1 l0 spectivo bear ngs, substantially as and for the purposespecified. r

In testimony whereof I alfix my signature in presence of two witnesses.
